Hair Extension

ABSTRACT

A hair extension and a method of attaching said hair extension to scalp hair. The hair extension comprises a plurality of hair strands, each hair strand having a first end and an opposing second end, and extending from a proximal end to a distal end. A weft is coupled to the plurality of hair strands and extends substantially perpendicularly to said plurality of hair strands intermediate the first and second ends from the proximal end to the distal end of said hair strands to form a first portion between the first end and weft and a second portion between the weft and second end. The hair extension is attached to scalp hair by interweaving the first portion of a first hair extension to scalp hair beginning at the proximal end of the hair strands toward the distal end of the hair strands to forming braided section.

FIELD

The present disclosure relates to hair extensions, particularly to a hair extension that is weaved into scalp hair.

BACKGROUND

Hair extensions are natural or synthetic hairs that are attached to existing scalp hair to give the appearance of hair having different characteristics such as length, thickness, volume, texture, color and style.

Hair extensions can be attached to scalp hair by means of an adhesive, clip-on, loops, or sewing. However, these existing methods have significant disadvantages.

Adhesive methods require adhesives that may cause skin irritation and require special care to prevent the extensions from detaching. Clip-on methods add additional material and weight to the extensions and do not attach as securely as other methods. Loops require additional material and manufacturing steps. In addition, loops require tools to aid in the difficult and time-consuming process of threading or crocheting scalp hair through the loops in order to secure the same.

Sewing and crocheting requires scalp hair to be braided first. The scalp hair is braided to form tracks along the scalp. The tracks may run along only a portion of the scalp or zig-zag across the entire scalp towards the top of the head.

The hair extension used in the sewing method comprises a weft at one end that is sewn into the tracks of scalp hair with a needle and string. This is a time-consuming process and the sewing places stress on the scalp hair and scalp hair roots which can cause discomfort and damage. In addition, the use of a needle creates a risk of injury.

Furthermore, hair extensions that are sewed or crocheted to braided scalp hair tend to disconnect easily and therefore the life of such hair extensions is limited.

Therefore a need exists for a hair extension that is easier and cheaper to manufacture, is light-weight, minimizes irritation, securely holds in place, and is easier and faster to attach to scalp hair.

DETAILED DESCRIPTION

Certain terminology is used in the following description for convenience only and is not limiting. The article “a” is intended to include one or more items, and where only one item is intended the term “one” or similar language is used. Additionally, to assist in the description of the present invention, words such as top, bottom, side, upper, lower, front, rear, inner, outer, right and left are used to describe the accompanying figures. The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import.

Referring to FIGS. 1-4, an embodiment of a hair extension 100 of the present invention is shown. In general, the hair extension 100 comprises a plurality of hair strands 102 having a first end 104 and an opposing second end 106, and extending from a proximal end 110 to a distal end 112. The hair strands 102 may be natural hair, synthetic hair or a combination thereof. The hair strands can also be of various lengths, textures, thicknesses, and colors. As shown in FIGS. 1 and 2, a first side 118 of the hair extension 100 is a mirror-image of a second side 120 of the hair extension 100.

Referring again to FIGS. 1-4, the hair extension 100 further comprises a weft 108 between the first and second ends 104, 106 of the hair strands 102. In the exemplar embodiment, the weft 108 is stitched into the hair strands 102 using a non-irritable thread of the same color as the rest of the hair strands 102. In other embodiments, the weft 108 may comprise an adhesive, hair, or a combination of material capable of securing the hair strands 102 together. The weft 108 extends the length of the hair extension 100 from the proximal end 110 to the distal end 112 to form a curtain-like structure.

Still referring to FIGS. 1-4, in the exemplar embodiment, the weft 108 forms a first portion 114 between the weft 108 and the first end 104. The first portion 114 is substantially straight in order to facilitate braiding, which is explained in more detail below. Furthermore, the weft 108 is positioned about five inches from the first end 104 to optimize braiding with scalp hair. It is preferred that the hair strands 102 of the first portion 114 are synthetic with minimal lubricity such that it can securely hold silky scalp hair when interwoven therewith.

Again referring to FIGS. 1-4, in the exemplar embodiment, a second portion 116 is formed between the weft 108 and the second end 106. In this embodiment, the hair strands 112 of the second portion 116 are long and wavy. However, as shown in FIG. 10, in another embodiment the second portion 116 can have a curly wave. In other embodiments, the second portion 116 could have other styles. The second portion 116 can be chemically treated or heat-treated to create various permanent or semi-permanent styles. For example, the second portion 116 could be manufactured as a “Janet Yaky” style by forming the hair strands 112 and heat treating the same at 150 degrees Celsius for 60 minutes; a “Body Wave Curl” style by forming and heat treating at 170 degrees Celsius for 50 minutes; a “Soft Wave Curl” style by forming and heat treating at 180 degrees Celsius for 50 minutes; and a “Wand Curl” style by forming and heat treating at 180 degrees Celsius for 50 minutes. In addition, the end user can style the second portion 116 themselves including cutting it to the desired length.

The hair extension of the present invention provides many advantages, one of them being reduced manufacturing costs. That is, using only hair strands 102 and a weft 108 reduces manufacturing costs compared to other hair extensions with additional material.

Referring to FIGS. 5-9, an embodiment of a method of attaching the hair extension 100 of the present invention to unaltered scalp hair is shown. That is, one's hair need not be braided first (e.g., corn rowed) in order to attach the hair extension 100 of the present invention. The method comprises a first step of sectioning off a portion of existing scalp hair 112. In the exemplar embodiment, the existing scalp hair 122 at a bottom edge of the scalp is sectioned off.

Referring to FIGS. 6-8, the first portion 114 of the hair extension 100 is braided to the sectioned-off scalp hair 122 beginning at the proximal end 110 of the hair extension 100. This eliminates the time-consuming extra step of securing the hair extension 100 to the scalp hair 122 by sewing or other means. The braiding continues along the scalp to form a continuous braided hair track 124 above the weft 108.

As shown in FIGS. 6-7 and 11, in one embodiment, the track 124 starts from the scalp hair 122 at the bottom of the left side of the scalp and continues towards the back of the scalp ending at the bottom of the back of the scalp. A mirror-image second track (not shown) starts from the scalp hair 122 at the bottom of the right-most side of the scalp and continues towards the back of the scalp ending at the bottom of the back of the scalp. Additional tracks 124 are formed above the existing tracks 124 in the same manner, ending with tracks along the top of the scalp 200. In this embodiment, a separate hair extension 100 is used for each layer and the track 124 of each layer is concealed by the second portion 116 of the hair extension 100 above each track 124.

Scalp hair 122 at the top of the scalp is braided without the hair extension 100 then sewn to the two top tracks 124. This helps to conceal the wefts 108 of the top tracks 124 as well as any exposed scalp. By sewing only the top, substantial time can be saved over existing methods that require sewing the entire length of the tracks 124, less stress is placed on the hair reducing discomfort and damage, and the risk of injury from use of the needle is minimized.

In another embodiment, as shown in FIG. 12, one continuous track 124 is formed on the scalp by braiding in a zig-zag pattern across the desired area. The track 124 could begin at a bottom left side of the scalp, continue toward a bottom mid-portion of the scalp, then to a bottom right side of the scalp. The track 124 would then continue above the track formed on the bottom right side of the scalp, continue above the track 124 formed at the bottom mid-portion of the scalp, then to above the track 124 formed on the bottom left side of the scalp. This process is continued until the track ends at the crown of the head 200. In this embodiment, the first and second sides 118, 120 of the hair extension 100 are exposed in alternate.

Optionally, second hair extensions with a looped top portion (not shown) can be tied to the second portion 116 of the first hair extension 100 nearest the weft 108. The second hair extensions can be used to cover any portion of the scalp or weft 108 that remain exposed.

FIG. 9 shows the completed method of attaching the hair extension 100.

Each of the first and second portions 104, 106 could be modified by the technician during installation. For example, the first portion 104 could be shortened to accommodate for shorter scalp hair. The second portion 106 could be shortened to desired length and could also be styled as desired.

As shown and described above, the hair extension of the present invention and the method for attaching the same to scalp hair saves substantial time and energy. The present invention also provides a longer lasting, more natural look for people that desire to use hair extensions.
